For me, all cars I've added works without problems. With CLEO and GtxHook you can add your vehiclename without edit the .gtx file!
A question, How I can put sounds to another ID like 18xxx? in the VehicleAudioEditor the range its 400 (in my VehicleAudioEditor 398) and 615.
Can I put 398-18xxx without problems? What's about the middle IDs used by default by the game?
And... I think it is a big but; Now, I can't enter in Loco lo go and Wheel Art Angels, all cars have now Paintjobs and the added cars has got ever secondary color
Am I only or anyone has got the same problem?
Put in the tutorial the GtxHook system, it's great to added cars.
